This invention relates to a measuring device and, more particularly, to an improved device for measuring the width of continuous strip material.

It is an object of this invention to provide an improved device which will automatically determine the variations in the width of a continuous strip of metal.

it is another object of this invention to provide an adjustable device for measuring continuous strip metal and the'like having various widths.

It is a further object of the present invention to provide a device for measuring the width of continuous strip metal which will automatically adjust itself relative to the edges of the strip as the strip passes therethrough.

Various other objects and advantages of my invention will more fully appear in the course of the following specification, and will be particularly pointed out in the appended claims.

In the accompanying drawings, I have shown, for the purpose of illustration, one embodiment which my invention may assume in practice.

In the drawings:

Figure l is a front elevational view of the improved continuous strip measuring device of my invention;

Figure 2 is a sectional view taken on the line lib-Ii of Figure l;

figure 3 is an end view of the device looking from the left side of Figure l; and,

Figure i is an end view looking from the opposite end thereof.

ihe improved measuring device of my invention, as shown in the drawings, comprises a rectangularly shaped box-like supporting structure or frame 2, preferably made by fastening two channel-like members 3 together in spaced relationship, with the channels opposite each other, so that the flanged portions of the same will provide an inner track or guideway therebetween; the purpose or which will be described later in the specification. A screw-shaft i, having a right-hand threaded portion on one end thereof and a left-hand threaded portion on the opposite end, is centrally supported in the frame. preferably by means of a centrally located hearing member 5.

On one side of the center of the frame there is disposed a carriage t having a lower portion i extending between the channel-like members i! and having guide-wheels t which are adapted to ride on the flanged portions of the members i. The lower extending portion also carries a pair of threaded collars t which are adapted to co- (iDi. 33-min operate with the respective threaded portion of the shaft 41. There is located on the top of the carriage a bracket it which carries a freely rotatable vertical roller 'III which is adapted to contact one side or edge of the strip.

There is disposed on the opposite side of the center of the frame 2 a similar carriage i2 havinga lower portion it also extending between the members i, and having guide-rollers it which are also adapted to ride on the flanged portions of the members 3. This lower extending portion also carries a pair of threaded collars It which are adapted to cooperate with the threaded portion of that end of the shaft t. The upper portion of the carriage it has positioned thereon a movable bracket it having rollers i'i disposed therein which are adapted to cooperate with guide-grooves it in the upper part of this carriage. It also has a freely rotatable vertical roller it positioned thereon which is adapted to contact the other edge of the strip opposite the roller i i. There is also disposed on the carriage ii a segmental calibrated dial it having centrally located therein a suitable shaft 2i having a gear it centrally positioned thereon and 25 a counterweight 23 positioned on one end thereof in back of the dial, and a pair of hands or pointers 2i preferably positioned on the opposite endin front of both sides of the dial. The gear it is adapted to mesh with a gear-rack 2% carried by the upper portion of the movable bracket it on the carriage i2.

Preferably positioned adjacent one end of the frame 2 between the channel-like members i there is an upwardly extending bracket 26 having a calibrated dial it disposed at the top thereof. There is positioned centrally of the dial a stub-shaft it having a sprocket-wheel it arranged on one end thereof, preferably in the back of the dial, and a hand or pointer to on the opposite end thereof in the front of the dial. On the lower portion of the bracket 26 there is positioned a gear ill which cooperates with that end of the threaded portion of the shaft t. There is positioned on the bracket it immediately above the gear iii a stub-shaft if having a gear 33 on one end thereof which is adapted to mesh with the gear ii and a sprocket-wheel ti on the opposite end thereof. There is provided between the sprocket-wheel 29 and the sprocket-wheel M a chain it. The lower portion of the bracket 26 also carries guide-rollers 3% similar to the rollers t! and it.

There is also positioned adjacent this end of the frame 2, and preferably" attached to the W bracket 26, a reversible "motor 31 having a shaft 38 and a worm 38 positioned thereon which is adapted to mesh with a gear 40 positioned on the end of the shaft 4. i

There is positioned, preferably in the center of the frame 2, a bracket 4| on which there is suitaby arranged a pair of supporting rollers 42 which are adapted to hold up the center of the strip as it passes through the device.

In operation, the carriages 6 and I2, having contacting rollers ii and i9, respectively, are moved the proper distance apart for the strip to be measured by means of the motor 31 which turns the screw-shaft 4 through the gears 39 I and 40. As the screw-shaft 4 turns to move the 28 through the chain 35, which moves the pointmove the carriage er 30 to indicate on the dial 2'! the distance apart of. the carriages 6 and i2 at any position on the frame. This dial is so calibrated that the pointer will indicate thereon the corresponding distance between the adjacent sides of the opposed rollers I I and i9.

As the strlripasses continuously between the non-yieldable oller II and the roller l9 and in contact there th, the variations in width will 2 which, in turn, drives the shaft 2| through tile gear-rack 25 moving the pointer 24, indicati g on the segmental dial 2!! the variations in width of the strip as it passes therealong. This dial 20 is calibrated to indicate, preferably in inches, the over and under variations in width of the strip.

It will be understood that the carriage is so arranged that the pointer 24 is normally at zero. The roller I9 is kept in contact with the edge of 40 the strip, preferably by means of the counterweight 23, but any suitable spring arrangement may be provided.

If the edge of the continuous strip has a camber or uneven edge contacting the roller ll,

it moves completely to either side of its regular path, moving the entire measuring device; that is, the carriages 6 and I2 and bracket 26, having guide-rollers 8, I4 and 36, respectively, will move in the channels of the frame, keeping the roller II always in contact with the edge of the strip, thus avoiding any error which would otherwise result if the device were stationary.

It will be apparent to those skilled in the art that the strip may enter the width measuring device of my invention without the need of a guiding mechanism and that the measurements of the width will be accurate even in the absence of such an auxiliary guiding means.

While I have, in this application, specifically 00 shown and described an embodiment of my invention, it will be. understood that this embodiment is merely for the purpose of illustration and description',""and that various other forms may be devised within the scope of the invention, as defined in the appended claims.
